Specification of Letters Patent.

Application filed December 19, 1914. Serial N o. 878,093.

T 0 all whom it may concern:

Be it known that I, CLEMENT V. Hna., a. citizen of the United States of America,

residing at Trenton, in the county of Mercer v and State of New Jersey, have invented certain new and useful Improvements in Heaters for Broodeis, of which the following is a specification.

In the use of a coal stove for heating brooders one of the greatest problems is to revent the escape of coal gas into the roomV in which the brooder is located. This is especially true in connection with self feeder or magazine stoves. It is desirable to use a magazine stove in brooders so as to reduce to a minimum the liability of the lire burning out. v

One of the objects of my invention is to provide a brooder heater stove in which there is a gas chamber between the top of the magazine andthe top` vof the stove and to provide means whereby said chamber is always in communication with the stove pipe, without affecting the draft of the stove,

vsaid gas chamber being separated yfrom the direct smoke passage in the stove.l Another object of my invention is to provide an automatic regulator for the stove.

A still further object of my invention is to so construct the stove, regulator, and associated parts in such manner that the n brooder hood is free to be raised and lowered without disturbing the parts of the stove and regulator and with these and other objects in view my inventionconsists of the kparts and A,combination of parts as will be hereinafter set forth. v

In the drawings: Figure 1 is a central vertical section of a brooder embodying my invention. Fig. 2 is an enlarged detail sectional view showing the joint between the stove and magazine and between the stove top and hood. Fig. 3 is a vertical sectional View of anotherembodiment of my invention.`

' 'The reference numeral 1 designates a stove having a lire box 2, an ash chamber 3, and ash door 4"., The ash chamber is also provided with a draft opening having a door 5.

The to plate 6 of the stove has ,a peripheral ange 7 inclined downwardly at an angle less than a right angle to provide .a

' bearing surface for the hood as will be hereinafter explained#l A smoke hole`8 is pro-A vided in t e top plate 6, the stove wall being deiected as at 9 under said smoke hole.

In the centei' of the top plate 6 and central with the axes of the stove an opening 10 is formed,the walls of which are ybeveled as at 11 in which the magazine is sus ended.

The magazine 12 extends into thek re box Patented Sept. 7, 1915.

2 the proper distance and is held in position by means of an annular beveled flange 1'3 engaging the beveled wall of the opening 10 in the top plate, the two bevels being formed on the saine angle so that they it with a practically gas tight joint. The top of the magazine terminates in a fiared collar oi' flange 14, the angle of flare being the saine as the angle of bevel ofthe wall of the opening 10 in the top plate 6. A valve 15 having a beveled periphery is adapted to vfit in said collai` 14: of the magazine with practically a gas tight joint. Now if for any reason it is desired to dispense with the magazine, it may readily be withdrawn from the stove and the valve 15 used to close the opening 1() in the plate 6. The valve 15 is provided with an operating handle 16 having an elongated stem 17.

On the top of plate 6 I secure a member for gas from thevchamber 21 into the cham# bei` 22, the chamber 22 being at all times opento the stove pipe 23. The bottom of the smoke vchamber 22 is provided with an opening establishing communicationv b ef tween said chamber and the fire box; the walls o'f this opening are beveled as shown 1n the drawing. A damper 24 having a beveled periphery is adapted to close this opening inthe bottom of the smoke chamber to stop the draft, said damper being carried by an arm 25 pivotally mounted as at 26,

the outer end of the arm projecting outside the smoke chamber. Now when the damper 24 is in closed position the pressure of gas in the stove is sometimes sufficient to cause it to leak around the periphery ofthe damper and the valve 15. From the smoke chamber 22 the gas will immediatelyvescape `to the stove pipe, but that leaking around the valve 15 would escape into the room and killthe chicks in the brooder. In order to prevent this I provide a lid 27 to cover the top of ioo stat in a frame to prevent greater diameteuthan the stem whereby a space is left around the stem, through which air is drawn by the natural draft of the stove pipe carrying the gas with it from the chamber 21. through ports 20 into the smoke chamber and thence into the smoke stack as indicated by the arrows. This draft is augmented by the fact that the door 28 of the smokeI chamber is open when the damper 2l is closed. This same draft of the stove pipe will naturally draw all the gas from the smoke chamber. In order to automatically control the damper and thus regulate theV heat of the brooder I provide any suitable commercial thermostat 29 and mount it in a suitable frame 30 attached to the base of the stove. I prefer to mount the thermothe chicks from roosting on it. A rod 31 is operatively connected to the thermostat'at at the top is provided' with a chain 32 the lower end of which is attached to the door 23 of the smoke chamberand constitutes a flexible connection between said rod and door thus permitting the door to swing in an arc on its hinges without affecting the vertical movement of the rod. A rod 33 is also connected to the thermostatand passes through the bottom of the frame 30, its lower end being pivotally secured to a lever 34 which is pivotally mounted on the lug 35 on the bottom of the frame. A chain 3G is connected to the opposite end of thelevcr 34 and to the air door 37 of the ash pit or chamber thereby establishing a flexible con-4 nection between said door and lever.

3S is a thermometer suspended from the frame. 30 near the floor. as it is at this point that the temperature of the room must be care-fully regulated because the lchicks are on the floor.

A hood 39, open at the top and bottom. is suspended from the stove top 6, and may be elevated, when necessary` by means of ropes 40 and running over the pulleys 41secured to the ceiling of the room. The upper part of the hood is inc-lined on the same angle as the fiange"7 thereby forming a tight joint therewith. while the upper edge or marginal portion of the hood is bent inwardly1 to constitute a flange 42 which rests on the upper face of the top plate 6 as shown.

The diameter of the opening in the top of the hood is such that will clear all working parts of the stove and regulator, whereby it may be raised and lowered withoutdisturbing any connection between the working parts of the organization.

It is obvious from the above description that if the temperature near the door falls below a predetermined degree the thermostat will automatically pull the rod 31 downthe bottom and ward. thereby closing the door 28 of the smoke chamber, and by reason of the pivotal` connection 43 between the outer end of the arm and rod 31, open the damper 21 and simultaneously, through the rod 33, lever 34, and chain 36, open the air door 37 in the ash pit or chamber thus admitting air to the fire box and permitting the fire to start up. lVhen the predetermined high degree of temperature is attained the thermostat will be again operated and restore the parts to the positions indicated in Fig. 1.

It will also be seen that chambers are provided above the top of the magazine 12 and above the stove damper 21, both of which are at all times in communication with the stove pipe 23 thus insuring the passage of all gases escaping from the stove directly into the smoke pipe thereby eliminating the escape of' the gasesv in the room. This is very important as coal gas will surely kill the chicks.

As shown in the drawing an arm 4l is pivotally mounted on the frame and connected with the thermostat, and a lever 15 pivotally mounted on said arm, the rods 31 and 33 being connected to said lever. 4G is a counterbalance mounted on the Ylever 45.

In Fig. 3 the damper 1G, air door HV17 ash ydoor 18 are substantially of the same construction shown in Fig. 1 and they are connected to the thermostat lrod 19 as shown 1n Fig. 1. I provide in this construction a peep hole to ena-ble the operator to ascertain the condition of the lire at any time without raising the hood and without disturbing any of the operating parts, but make this opening of a very small diameter to reduce to a minimum the liability of the escape of gas. The peep opening is made by forming a hole in the top wall of the chamber 18a and an opening in the top plate G of the stove in alinement with each other. These openings are closed by means of lids 50 and 51 rigidly mounted on and carried by the rod 52, the upper end of which terminates in a suitable handle 53, whereby7 the lids may be removed to enable the operator to look downupon th'e'fire between the magazine feeder 12a and the side of the stove. The hood 39a is ofthe same construction as heretofore describedi/'while .the body of the stove 1 is of different construction in that at the top the walls areflared out, as at 54;,

me to conveniently locate the peep hole between it and the magazine.
